Which animal has 4 stages of life cycle?
Some animals, such as mealworm beetles, butterflies and mosquitoes, have four stages in their life cycles.
The four stages are the egg, the larva (plural: larvae), the pupa (plural: pupae) and the adult.
The young of these animals look different from the adults.
They undergo metamorphosis..
What are some examples of animals that go through metamorphosis?
Examples of metamorphosis include the tadpole, an aquatic larval stage that transforms into the land-dwelling frog (class Amphibia). Starfishes and other echinoderms undergo a metamorphosis that includes a change from the bilateral symmetry of the larva to the radial symmetry of the adult.
What means life cycle?
1 : the series of stages in form and functional activity through which an organism passes between successive recurrences of a specified primary stage. 2 : life history sense 2. 3 : a series of stages through which something (such as an individual, culture, or manufactured product) passes during its lifetime.
Is reproduction a life process?
The basic processes of life include organization, metabolism, responsiveness, movements, and reproduction.
What is a plant life cycle?
The Life Cycle of a Plant The plant starts life as a seed, which germinates and grows into a plant. The mature plant produces flowers, which are fertilised and produce seeds in a fruit or seedpod. The plant eventually dies, leaving seeds which germinate to produce new plants.
What are the four stages of life cycle?
The life cycle has four stages – introduction, growth, maturity and decline.
Do plants have a life cycle?
All plants have a life cycle with alternation of generations. Plants alternate between diploid sporophyte and haploid gametophyte generations, and between sexual reproduction with gametes and asexual reproduction with spores.
Which life cycle is the simplest?
haploid life cycleThe haploid life cycle is the simplest life cycle. It is found in many single-celled eukaryotic organisms.
At what stage of its life cycle does an animal reproduce?
AdultAdult-the stage of an animal’s life cycle when it reproduces. Egg-a structure containing food that young animals need in order to grow. Hatching- the process by which an animal breaks out of an egg. Larva-a young insect that has just hatched.
Which animal has the longest life cycle?
bowhead whalesThe quahog’s life-span is usually about 225 years. (Also see “405-Year-Old Clam Called Longest-Lived Animal.”) Some deep-sea fish, like the orange roughy, live to be 175 years old, according to the book Sexuality in Fishes. As far as mammals go, bowhead whales seem to have the most candles on their cake—over 200.
Which stage of life is most difficult?
AdolescenceAdolescence is the hardest stage for one’s life. There are too many drastic life changes like physical, psychological and behavioral changes going on in one’s life. It is easy for adolescents to get lost on their way in searching for the adult world by making mistakes.
Why do humans not have metamorphosis?
Metamorphosis does not take place in humans and other viviparous animals because their offspring are fully formed inside their mother’s womb. They do not need any further differentiation of their body parts. However, after their birth there is a further growth and development of the body parts to reach maturity.
Do all animals go through a life cycle?
Most classes of animals, including fish, mammals, reptiles, and birds, have fairly simple life cycles. First they are born, either alive from their mother or hatched from eggs. Then they grow and develop into adults. … These animals undergo a metamorphosis (a significant change in their physical structure or habits).
Do all animals start life as eggs?
Most animal species begin life as a single egg cell that is then fertilised by a sperm cell. … Animals are born in different ways depending on the group as mammals give birth to live young, where birds, fish and reptiles lay eggs which their young hatch out of.
What are the 7 stages of life?
Jaques divides the life of a man into seven stages:Baby or infant.School boy or child.Lover.Soldier.Justice or judge.Old man.Extreme old age, again like a child.
What are the 12 stages of life?
The major stages of the human lifecycle include pregnancy, infancy, the toddler years, childhood, puberty, older adolescence, adulthood, middle age, and the senior years.
What is butterfly life cycle?
The butterfly and moth develop through a process called metamorphosis. This is a Greek word that means transformation or change in shape. There are four stages in the metamorphosis of butterflies and moths: egg, larva, pupa, and adult. …
What animals change as they grow?
Metamorphosis means a change in body form. It causes big changes in insects such as the butterfly and smaller changes in insects such as the grasshopper. Other animals, such as frogs and toads, also go through metamorphosis. For example, young frogs live only in water.
